FW: FW: Turbo fever (aquamist) - water injection idea

Absolutely correct, It was a very inefficient and unscientific system,
mostly it just made me feel good about doing it, and kept the insides of my
engine clean (we don't need no steenkin Techron...).  In retrospect, I
probably should have used the vacuum to hold a spring loaded valve closed
and as engine speed increased, vacuum dropped and the valve would start to
open and allow more water into the engine.  When I get the landrover rebuild
done (with a NA Ford 302) I may try this.

I like your suggestion about pressurizing the water bottle - as a matter of
fact, it smacks of genius.  Pressurize the water bottle with the boost and
like you said, the more boost, the more water.....I think I may pursue
this.... will keep you all posted.
If I start doing stuff like this I better buy a g-tech pro first, so that I
can measure any performance gains (or losses:())
